Event Description
|
It was reported that stent damage and stent fracture occurred.A 28 x 4.00 promus premier¿ drug-eluting stent was selected to treat the target lesion.However, the physician could not get the device into the guide catheter.After examining the stent, the physician noted that some struts on the stent were fractured and some metal was sticking out.The procedure was completed with another of the same device.No patient complications were reported and the patient's status was stable.

Device evaluated by mfr: the stent delivery system (sds) was returned for analysis.A visual examination of the crimped stent found stent struts on the 6th row from the proximal end of the crimped stent were lifted upwards from the stent profile.An examination of the crimped stent found no stent strut fractures evident.The bumper tip of the device showed no signs of damage.The balloon cone profiles were reviewed and no issues were noted with the overall balloon profile.The balloon wings were tightly wrapped and evenly folded and were not subjected to positive pressure.A visual and tactile examination found multiple kinks along the hypotube shaft.This type of damage is consistent with excessive force being applied to the delivery system.A visual and tactile examination found that the inner wire lumen and outer shaft were damaged at the location of the bi-component bond.The damage evident may have prevented the tracking of the device over the guidewire during the procedure; however the device was successfully tracked over the guidewire during examination of the unit.The damage may have been caused by the product mandrel or guidewire while being tracked over by the device.There is no evident damage to the bi-component bond.No other issues were identified during the product analysis.The manufacturing batch record review confirmed that the device met all material, assembly and performance specifications.The most probable root cause is operational context as device performance was limited due to anatomical procedural factors.(b)(4).
